Abstract

A boat trailer has a base plate attached to the trailer fender. A hollow bar is pivotably attached at one end to the base plate and releasably fastened near its opposite end to the rear of the fender. A bracket for supporting a lamp and license plate is attached at the opposite end of the bar. Electrical wires extend from the vehicle's electrical system through the bar to the lamp. The bar is fastened to the base in such a fashion that the lamp and license plate are repositionable from the rear of the trailer where the lamp and license plate are located during over-the-road travel to a position forward of the fender prior to launching a boat from the trailer. In this regard, the bar is released from the fender and rotated 180° so that the lamp and license plate are forward of the fender whereby the lamp and associated electrical wiring will not contact the water during launching of the boat thus avoiding dangerous electrical conditions.

SUMMARY OF THE INVENTION

Boat trailers are required to have running lights so as to be visible during travel at nighttime. Due to electrical hazards which may occur during launching, it became evident that it would be advantageous to provide a support for the lights which would facilitate either removal of the lights from the trailer during launching of the boat or repositioning of the lights so that they would not contact the water causing dangerous electrical conditions or deterioration to the lights and associated electrical wiring.

One of the objects of this invention is to construct a support for boat trailer lamps and license plate which will be inexpensive to produce and simple to install.

Another object of this invention is to provide a support for boat trailer lamps and license plate which is adaptable to either single axle or double axle trailers.

It is yet another object of this invention to provide such a support for the trailer lamps and license plate in the form of a bar which is pivotably attached to a base plate on the trailer fender so that the lamps and license plate may be pivotably repositioned about a vertical arc to a location where they will not come in contact with the water during launching of the boat.

It is yet a further object of this invention to provide a support for boat trailer lamps and license plate which is in the form of a bar hingedly attached to a base plate on the trailer fender so that the lamps and license plate may be swung through a horizontal arc to a position where the lamps, license plate and electrical wiring will not contact the water during launching of the boat.

These and other objects of this invention will become apparent from a consideration of the specification when read in conjunction with the annexed drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A boat trailer 10 has standard multiple axle running gear with multiple wheels 12 and 14 (one for each axle shown) as best seen in FIGS. 2 and 7 or a single axle structure with wheels 16 (one shown) as best seen in FIG. 4. The trailer 10 has the usual cradle 20 for supporting a boat 22 having an outboard motor 24.

The wheels of the trailer 10 have fenders 26 (one shown) which span the

multiple wheels

12 and 14 as best seen in FIGS. 2 and 7 or fenders 28, (one shown) for the single axle trailer as best seen in FIG. 4.

A base plate 30 in the form of a hollow bar, FIGS. 2 and 3, is fastened to the fender 26 by suitable nuts and

bolts

32 and 34. This hollow bar is rectangular in configuration but any other configuration also may be used. A second hollow bar 36 is hingedly connected to the plate 30 by a hinge 38 having connecting

arms

40 and 42 securely fastened to each of the bars by suitable nuts and bolts shown generally by the numeral 44.

The bar 36 is also rectangular in configuration, however, as in the first bar, any other form may be used. The bar 36 is pivotable about the horizontal axis 46 so that the bar may be swung 180° about a vertical arc as shown by the arrow in FIG. 2.

A bracket 48 has a front lower surface 50, upper surface 51,

extension arms

52 and 54 and rearwardly extending

parallel arms

56 and 58 having

apertures

60 and 62 therein. The

arms

56 and 58 are designed to telescope over

sides

66 and 68 of the end 70 of the bar 36. The bracket 48 is secured to the end 70 of the bar 36 by inserting a bolt 72 through the

apertures

60 and 62 in the

arms

56 and 68 and through an aperture 74 in the base. A nut 76 secures the bracket in place.

A lamp 78 is fastened to the upper front surface 51 by suitable bolts (not shown) and electrical wires 80, FIGS. 2 and 3, extend from the towing vehicle's electrical system through the hollow bars to the lamp 78. Identification indicia such as a licensed plate (not shown) may be mounted on the lower surface 50 of the bracket 48.

When the boat 22 is being towed to or from the launching ramp, bar 36 is oriented such that the lamp 78 and identification indicia extend beyond the rear of the boat as is required. A hand manipulable nut and bolt 84 is used to secure the bar 36 to the fender 26 during over-the-road travel. When the boat 22 is to be launched, the nut and bolt 84 is removed by hand and the bar 36 is then swung 180° through a vertical arc about lthe pivot axis 46 until the bar lies over and flat against the base 30. By this construction, the lamp 78 and the electrical wiring 80 are repositioned to a forward location where they will not get wet when the trailer is lowered down the ramp and into the water as best seen in FIG. 1.

The advantages of this arrangement over the prior art is the ease by which the trailer lamp support bar may be attached to the trailer fender for normal over-the-road travel and repositionable to a forward position during launching of the boat. This device provides a simple structure which is easily installed and yet provides a means for lessening or eliminating the hazards of electrical shocks due to deterioration of the trailer lamp and the associated electrical wiring as a result of constant contact with the water during launching.

A modified form of the invention is shown in FIGS. 4 and 5. A solid base bar 82 is fastened to the fender 28 by

brackets

84 and 86 and nuts and bolts 88. A hollow bar 90 similar to bar 36 is pivotably attached to the bar 82 by a bolt 92 which extends through apertures 94 (one shown in the bar) and aperture 96 in the bar 82. When the trailer is being hauled over the road, the bar 90 with lamp 78 and identification indicia such as a license plate (not shown) is in the rearward position such that the lamp 78 and license plate are behind the trailer as is required. A bolt 98 extends through apertures 99 (one shown) in bar 90 and through an aperture 100 in the bar 82. Prior to launching the boat from the trailer into the water, the bolt 98 is removed by hand and the bar 90 is rotated 180° about the vertical axis of the bolt 92 to a position forward of the trailer fender 28 as best seen in FIG. 4. Electrical wires (not shown) extend from the towing vehicle's electrical system through the hollow bar 90 to the lamp 78.

This device provides a simple structure which is easily installed on the fender of a single axle boat trailer and permits the trailer lamp to be easily and readily repositioned from an over-the-road running position to a position forward of the fender where the lamp and associated electrical wires will not contact the water during launching of the boat.

A further modification of the invention is shown in FIG. 7 and 8. Instead of the separate base bar and

brackets

82 and 84 and 86, respectively, a unitary base plate 102 having a top horizontal portion 104 and a downwardly an inwardly extending portion 106 is provided. The end 108 of the base plate is fastened to the upper flat surface 110 of the fender 26 by suitable bolts 112 (one shown). The lower end 114 of the portion 106 is a foot which is fastened to the lower end 116 of the fender by suitable bolts 118 (one shown). A hollow bar 119 is pivotably mounted to the top horizontal portion by a bolt 120. In the over-the-road running condition, the bar 119 is fastened to the top horizontal portion 104 by a suitable hand manipulable bolt 122 so that the lamp 78 and license plate are at the rear of the trailer. Prior to launching the boat, the bolt 122 is removed by hand and the bar 119 swung 180° on the vertical pivot axis of the bolt 120 to a position where the lamp 78 and license plate are forward of the fender 26. An L-shaped bracket 124 secured to the forward end of the fender is adapted to prevent the bar 119 from striking the boat or alternatively to provide a means for securing the bar to the bracket while the boat is being launched.

This device provides a standard base plate adaptable to either the fenders of dual axle trailers or the fenders of single axle trailers. As in the other modifications, this device permits the simple and easy installation of a trailer lamp and license plate support so that the movement of the lamp and license plate from an over-the-road position may be accomplished by simply releasing the bar upon which the lamp is supported and rotating same to a position where the lamp is forward of the fender. Thus, it will be readily evident that by repositioning the lamp forward of the fender, the lamp and associated electrical wiring will not contact the water and thus serious electrical hazards will be prevented.

While the invention has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that various changes in the form and details may be made therein without departing from the spirit and scope of the invention.
